A man who met his long-lost brother for the first time after 50 years despite living just a mile away from him has died suddenly.

In a heart-wrenching episode of ITV's Long Lost Family, viewers were introduced to Steve Belshaw, 54, from Blackpool, who was looking for his mother, who placed an advert in her local paper to find new parents for her son when she was a teenager.

Through the show, Mr Belshaw learned he had a half brother, Robert, 45, living just a mile from him in Lancashire.

But Mr Belshaw died earlier this month, just two weeks after the show aired, it can be revealed.

Mr Belshaw, 54, from Blackpool, was devastated when he was told the birth mother he was hoping to meet had died. But he was later introduced to his half-brother Robert, 45, who has been living just a mile away. Pictured is the moment the brothers met for the first time

The cause of his death is currently unknown and friends on Facebook have been paying tribute to him.

His partner Kelly told the Daily Mirror: 'I don't know what to say other than we're devastated and he's been taken from us far too soon.'

Mr Belshaw, an environmental consultant, only had two letters to remind him of his mother Frances, which she had written to his adoptive parents.

It transpired that Frances decided to give Mr Belshaw up for adoption when she was just 18 because her boyfriend, his father, died while she was pregnant with him.

She advertised for prospective adoptive parents in the local newspaper and chose a local Blackpool family, who didn't see her again once she handed Mr Belshaw over to them.

Speaking on the show, he said he didn't feel any resentment towards his mother for giving him away, telling the cameras: 'I think it's extremely unusual to advertise your unborn child but it's an extraordinarily loving thing to do.

'Knowing that she went to all that trouble to find the best parents she possibly could find to me speaks volumes about her character.'

Long Lost Family presenters Nicky Campbell and Davina McCall tracked Frances down via her marriage certificate, and from this were able to find her death certificate.

Robert did know about Mr Belshaw's existence as Frances had told him when he was just 10

They found out that Frances had another son, Robert, who knew that Mr Belshaw existed but didn't know how he was put up for adoption or where he was.

Robert, who lives with his partner Kelly and their six children, agreed to meet him in Stanley Park, where both men had played as children.

When they met for the first time the brothers shared a long hug, and Robert told his brother stories about their mother.

Robert said: 'She always said to me that your dad was the love of her life and when he died it just destroyed her.'

When they met, Robert showed Mr Belshaw photographs of his mother as a young woman, pictured

Mr Belshaw was overwhelmed that his mother hadn't forgotten him and told his brother about him, and said: 'I've carried that hope with me for my entire life. To know that makes me so enormously happy.'

He was introduced to Robert's children, and the brothers said they were looking forward to getting to know each other.

Mr Belshaw said: 'We share a very, very similar sense of humour and a similar outlook on life. It's very natural.'
